As defined by the US National Cholesterol Education Program Adult Treatment Panel III guidelines, an HDL cholesterol level (HDL-C) of 60 mg/dL or greater is a negative (protective) risk factor.On the other hand, a high-risk HDL cholesterol level is described as one that is below 40 mg/dL.
Spica or Alpha Virginis (Alp Vir) is the brightest naked eye star in the constellation Virgo. With an apparent magnitude of 0.98v, Spica is the 15th brightest star in the entire sky (see: 50 Brightest Stars).Its absolute magnitude is -3.55 and its distance is 262 light years.The Equinox J2000 equatorial coordinates are RA = 13h 25m 11.6s, Dec = -11Â° 09' 41.pica has a spectral type of B1V, a surface temperature of 22,400Â° Kelvin and a luminosity 12,100 times the Sun. It has a mass of 10.3 solar masses and a diameter 7.4 times the Sun. The image above shows the uncropped view of Spica (North is up) through the Takahashi E-180 Astrograph.
What is the biggest star we know? The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy. In 1995, it was suggested that the Pistol Star was so massive it was throwing off the mass that actually created the Pistol Nebula.
